Abstract

Conventional diesel and soybean-based biodiesel blends were analyzed as the fuel of a direct injection (DI)

compression ignition engine in order to investigate their performance and suitability. The tests were conducted on an

air-cooled single cylinder DI diesel engine. Engine torque, brake power, and brake-specific fuel consumption results

associated with each of these fuel blends were collected under certain operating conditions. The CO2, CO, and NOx

emissions were measured and the in-cylinder pressure was collected and analyzed.

The performance characteristics of soybean–diesel blends were similar to those of conventional diesel fuel and the

blends showed slightly higher torque and power output compared to the conventional diesel fuel. The results indicate

that the soybean ester has great potential as an alternative fuel for diesel engines.
